The age range of the sampled adolescents was 13\u201318 years, and none of them had any history of orthodontic treatment. A survey chart related to malocclusion was designed and filled up after clinical examination by a single experienced and calibrated examiner. The need for orthodontic treatment was assessed using the Index of Orthodontic Treatment Need (IOTN).<\/jats:p>\n <\/jats:sec>\n \n RESULT:<\/jats:title>\n The present study's findings demonstrated 61.2% of the samples with Angle's Class I malocclusions, 27.5% with Class II, and 11.4% of samples with Class III malocclusion. A significant difference was observed between the different classes of malocclusion (P < 0.001). Most samples presented normal overjet, crossbite, and no reverse overjet, deep bite, or open bite. The number of samples with no treatment need was 573 (52.37%), with slight treatment in 185 (16.91%) samples, moderate treatment needs in 123 (11.24%) samples, and severe and extreme treatment needs were 109 (9.96%) and 104 (9.50%), respectively. A significant difference was observed between the samples with no or slight treatment need (grades 1 and 2), moderate need (grade 3), and definite treatment need (grades 4 and 5) (p < 0.001).<\/jats:p>\n <\/jats:sec>\n \n CONCLUSION:<\/jats:title>\n The prevalence of malocclusion and IOTNs among the sample of school-going adolescents in the Najran city was 47.63%. However, 9.63% of those samples required immediate attention for orthodontic treatment.<\/jats:p>\n <\/jats:sec>","DOI":"10.4103\/jos.jos_51_23","type":"journal-article","created":{"date-parts":[[2023,9,6]],"date-time":"2023-09-06T02:15:40Z","timestamp":1693966540000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":9,"title":["Prevalence of malocclusion and orthodontic treatment needs among adolescents in Najran City, Saudi Arabia"],"prefix":"10.4103","volume":"12","author":[{"given":"Dhafer","family":"Alyami","sequence":"first","affiliation":[{"name":"Department of Orthodontics, Specialized Dental Center, Ministry of Health, Najran, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adel","family":"Alharbi","sequence":"additional","affiliation":[{"name":"Department of Orthodontics & Pedodontics, College of Dentistry, Qassim University, Abha, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yousef","family":"Hatan","sequence":"additional","affiliation":[{"name":"Ministry of Health, Abha, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yahya M.","family":"Asiri","sequence":"additional","affiliation":[{"name":"Ministry of Health, Abha, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hussein","family":"Alharthy","sequence":"additional","affiliation":[{"name":"Department of Pedodontics, Ministry of Health, Jeddah, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yahya Abdullah","family":"Alogaibi","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Ministry of Health, Abha, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2023,9]]},"reference":[{"key":"R1-20240830","doi-asserted-by":"crossref","first-page":"43","DOI":"10.1111\/j.1834-7819.1996.tb05654.x","article-title":"Establishing malocclusion severity levels on the dental aesthetic index (DAI) scale","volume":"41","author":"Jenny","year":"1996","journal-title":"Aust Dent J"},{"key":"R2-20240830","first-page":"207","article-title":"Epidemiologic panorama of dental occlusion","volume":"60","author":"El-Mangoury","year":"1990","journal-title":"Angle Orthod"},{"key":"R3-20240830","first-page":"12","article-title":"The Prevalence of malocclusion in Swedish schoolchildren","volume":"81","author":"Thilander","year":"1973","journal-title":"Scand J Dent Res"},{"key":"R4-20240830","doi-asserted-by":"crossref","first-page":"253","DOI":"10.1111\/j.1600-0528.1990.tb00070.x","article-title":"Prevalence of malocclusion and need for orthodontic treatment in Saudi Arabia","volume":"18","author":"Al-Emran","year":"1990","journal-title":"Community Dent Oral Epidemiol"},{"key":"R5-20240830","doi-asserted-by":"crossref","first-page":"477","DOI":"10.1093\/ejo\/cjp031","article-title":"Malocclusion and occlusal traits in an urban Iranian population.
